“…Biodivers Conserv (2012) 21:1997-2015 Although some studies indicate that macroinvertebrate communities can resist change to disturbances through rapid colonisation and use of alternative refugia (Collier and Quinn 2003), this study suggests that adaptive responses to invasive predators may differ in habitats with and without fish. Macroinvertebrates in fish-containing habitats tend to develop anti-predator responses to fish (Schilling et al 2009). In addition, within habitats where invasive predators have establishment, macroinvertebrates may evolve to become less vulnerable through behavioural and morphological adaptations in response to predation (Simon and Townsend 2003;Abjornsson et al 2004;Meissner and Moutka 2006;Kitano et al 2009).…”

“…Natural fish populations are typically limited in both abundance and diversity in ponds and their influence on the functioning and structure of ponds is reduced compared to larger lakes (De Meester et al, 2005). However, many anthropogenically created ponds and shallow lakes are stocked with fish for angling or ornamental purposes (Wood et al, 2001;Hassall, 2014) and fish have been demonstrated to influence invertebrate composition (Wood et al, 2001;Schilling et al, 2009;Beresford and Jones, 2010;Chaichana et al, 2011) and cause trophic cascades (Nyström et al, 2001;Knight et al, 2005) in both lakes and ponds. The smaller catchment area of ponds compared to larger lakes can enable quite different environmental conditions to develop (reflecting local microsite conditions (Scheffer et al, 2006)) even in ponds that are in close geographical proximity to each other Davies et al, 2008b).…”

Ponds are common and abundant features in nearly all landscapes typical of European lowland landscapes yet research on freshwater biodiversity has traditionally focussed on larger waterbodies such as lakes and rivers. This has led to an increased need to understand and quantify the biodiversity associated with pond habitats to better inform the active conservation and management of these small waterbodies. This thesis examines the aquatic macroinvertebrate biodiversity (alpha, beta and gamma) and conservation value of 95 ponds in Leicestershire, UK, across a variety of urban and rural landscape types and at a range of spatial scales. In addition, the relative importance of local (physicochemical and biological) and spatial (connectivity) variables in structuring macroinvertebrate communities within ponds is investigated. At a regional scale, the greatest macroinvertebrate biodiversity and conservation value was recorded within meadow ponds compared to urban, agricultural and forest ponds. Spatially, ponds were highly physically and biologically heterogeneous. Temporally (seasonally), invertebrate communities were most dissimilar in meadow and agricultural ponds but assemblages were similar in urban and forest ponds. In urban landscapes, park ponds supported a greater diversity of invertebrates than 'other' urban or garden ponds and typically had a greater conservation value. Garden ponds were the most taxon poor of those investigated. Perennial floodplain meadow ponds supported a greater biodiversity of invertebrates compared to ephemeral meadow ponds although conservation value was similar. Despite regular inundation from the River Soar, ephemeral ponds supported distinct communities compared to perennial meadow ponds. Aquatic macrophytes supported a higher diversity of taxa than other pond mesohabitats across all landscapes studied. Physicochemical factors were identified to be the dominant influence on macroinvertebrate assemblages although, a combination of local and spatial factors best explained the variation in community composition at a regional scale and for meadow ponds. Spatial factors were not identified to significantly influence urban pond communities. This study highlights the ecological importance and conservation value of ponds in rural and anthropogenically disturbed landscapes. Recognition of the significant contribution of ponds to freshwater biodiversity at regional and landscape scales is important for future conservation of pond habitats and will help focus and direct conservation strategies to where they are needed most.iv

“…This is evidence of the broad composition of littoral fauna being highly resilient to vertebrate predation. It is possible that predators were size selective, affecting the abundance of easily accessible groups, such as chironomids (Orthocladiinae and Chironominae) and planktonic crustaceans (Kernan et al, 2009;Syväranta and Jones, 2009;Schilling et al, 2009). Another explanation is that the generally coarse littoral substrate together with shielding mechanisms insects use in alpine lakes to protect against high solar radiation could also be effective against vertebrate predation.…”

In low nutrient alpine lakes, the littoral zone is the most productive part of the ecosystem, and it is a biodiversity hotspot. It is not entirely clear how the scale and physical heterogeneity of surrounding catchment, its ecological composition, and larger landscape gradients work together to sustain littoral communities.A total of 113 alpine lakes from the central Pyrenees were surveyed to evaluate the functional connectivity between littoral zoobenthos and landscape physical and ecological elements at geographical, catchment and local scales, and to ascertain how they affect the formation of littoral communities. At each lake, the zoobenthic composition was assessed together with geolocation, catchment hydrodynamics, geomorphology and topography, riparian vegetation composition, the presence of trout and frogs, water pH and conductivity.Multidimensional fuzzy set models integrating benthic biota and environmental variables revealed that at geographical scale, longitude unexpectedly surpassed altitude and latitude in its effect on littoral ecosystem. This reflects a sharp transition between Atlantic and Mediterranean climates and suggests a potentially high horizontal vulnerability to climate change. Topography (controlling catchment type, snow coverage and lakes connectivity) was the most influential catchment-scale driver, followed by hydrodynamics (waterbody size, type and volume of inflow/outflow). Locally, riparian plant composition significantly related to littoral community structure, richness and diversity. These variables, directly and indirectly, create habitats for aquatic and terrestrial stages of invertebrates, and control nutrient and water cycles. Three benthic associations characterised distinct lakes. Vertebrate predation, water conductivity and pH had no major influence on littoral taxa.This work provides exhaustive information from relatively pristine sites, and unveils a strong connection between littoral ecosystem and catchment heterogeneity at scales beyond the local environment. This underpins the role of alpine lakes as sensors of local and large-scale environmental changes, which can be used in monitoring networks to evaluate further impacts.
